Pronotum proportionately less ample and less transverse than in nitidida; well 

 supplied with very minute hairs, these decidedly less numerous and not elongate on 

 the cephalic and lateral margins as in nitidiila; surface weakly convex, becoming 

 strongly so laterad; cejihalic and caudal margins transverse, lateral margins weakly 

 divergent caudad and weakly convex; latero-cephalic angles very broadly rounded 

 and very broadly obtuse-angulate, latero-caudal angles broadly rounded, forming 

 an angle of slightly more than ninety degrees. Scutellum proportionately large, 

 smooth, without hairs. Tegmina proximad opaque, smooth, without hairs, bound- 

 ed by a straight oblique line from apex of scutellum to apex of discoidal vein; 

 remaining distal portion delicate, suffused, hyaline. 



Cerci as in niiidida, with (eight) strongly defined, rounded joints. Supra-anal 

 plate decidedly produced, free margin rather strongly convex. Subgenital plate'^s 

 with surface convex, deeply and sharply acute-angulate emarginate in mesal quar- 

 ter, this area occupied by two vah'es, with surfaces weakh' concave, separated by a 

 medio-longitudinal cleft. 



Cephalic femora with ventro-ce[)halic margin armed with a row of minute chaeti- 

 form spines, succeeded by two heavy, elongate, distal spines, of which the last is 

 much the longer; other ventral femoral margins unarmed. Tarsi very slender; 

 caudal metatarsus longer than combined length of succeeding joints, its ventral 

 surface armed with a double row of microscopic chaetiform spines; minutely micro- 

 scopic pulvilli appreciable only, situated distad on first and second joints, filling 

 ventral surfaces of third and fourth joints. Moderately well developed arolia 

 present. 



Length of body, 5; length of pronotum, 1.4; width of pronotum, 1.7; length of 

 tegmen, 4.65; width of tegnicn, 1.8; length of caudal tibia. 1.8 mm. 



Head blackish mummy brown. Antennae of same color, with a broad bufiy 

 annulus (which occupies four to six joints) meso-distad. Pronotum with a 

 broad medio-longitudinal suffused band of blackish mummy l)rown, which expands 

 evenly caudad, nearly twice as broad at the caudal margin as at the cephalic margin; 

 pronotum laterad light ochraceous-buff, tinged with ochraceous-orange mesad 

 toward the median band. Proximal opaque portion of tegmina blackish mummy 

 brown, with a very feeble metallic purplish sheen; distal portions of tegmina hyaline, 

 tinged with mummy brown. Ventral surface and limbs dark mummy brown, except 

 proximal two-thirds of median and caudal femora, which are pale ochraceous-butT. 



The type is unique.

This diminutive insect is remarkable in ha\'ing the tegmina 

 entirely clear hyaline, except for a narrow marginal area which 

 expands slightly twice along the costal margin and a very narrow

 the species of the genus Holocompsa.
